Question
Find the median and mean of the data set below:45, comma, 8, comma, 25, comma, 3845,8,25,38
Solution
Sure, let's start with the mean first.
Step 1: Add all the numbers together. 45 + 8 + 25 + 38 = 116
Step 2: Divide the sum by the total number of data points. 116 ÷ 4 = 29
So, the mean of the data set is 29.
Now, let's find the median.
Step 1: Arrange the data in ascending order. 8, 25, 38, 45
Step 2: Since there are 4 numbers (an even number), the median is the average of the two middle numbers. (25 + 38) ÷ 2 = 31.5
So, the median of the data set is 31.5.
